March 5 127. j l v I This invention relates.\ to an vautomatic charging hopper for receptacles of any kind, espe'ciallyifor' producers. The charging device is intended. to feed material to thereceptacle inv predetermined intervals over, the, entire surface of thesame and uniformly; independently ofthe grain-size of the charging material.

Charging apparatus for receptacles, and the like general-lyin use have thedisadvan tages that they can operate efliciently only upon a certain sized grain of material Itis, therefore, the object of this. invention to provide a machine of thischaracter for use with miscellaneous; sized grains, thusprovidin'gin reality a universal apparatus. 1

.In the charging hopper according to Y the invention a' predetermined quantity of material is separated in-a rotatable charging shaft of cylindrical :or] other, convenient shape by tworotatable disks. This rotatable charging shaft is inclined so that larger surfaces can be charged centrally from the centre. HA distributor arranged underthe charging shaft distributes the material over larger surfaces. The rotatable charging shaft is opened and closed by the two rotatable discs at predetermined intervals.

An embodiment of the invention is illusviewed from below.

The material to be distributed is fed into thecharging hopper from the supply or directing tube a which is arranged at the side of or above said charging hopper.

In the charging hopper a rotary cut-01f disk I) is arranged mounted to control the upper end of a charging tube 0, said cover being provided with the discharge aperture 6 adapted to aline with the tube 0. The upper open end of the charging tube 0 is arranged in the axis of rotation of the charging hopper and the tubeis inclined away from the vertical. The tube 0 rotates in a casing cl, so that its lower open end moves in a circle on a disc e which has an opening 6 so that the outlet opening, of the charg- The charging apparatus is operated from a-shaft .g mounted at'the side of the Taxis of the chargingapparatus and saidshaft carries a pinion h and also the rotatable disc which meshes with a toothed crown 00i disk e. -The pinionm rotates therefore-said ried as well by altering the ge'ar,wheel transm1ss1on.- At every 'rota'tionffof diske the opening 6 may be brought into'fregistei'; T
